Must there be specific conditions for regenerating the images?

    Hi,

    I have used this plugin for more than four months, but images which have been regenerated are about 20mb, too small.

    I saw just some images were regenerated when I checked Cache folder. Although there are a lot of images in my EC site, why so little amount of images were regenerated?

    Are there any problem on my setting, by any chance?

    Could I set my plugin to regenerate all of my images?

    Thank you.

    Hello, my friend,

    First of all, the Adaptive Images plugin only creates images in the cache when it is necessary to do so, in order to reduce the possible server load. This means that, if an image is not requested by a device small enough (ie small enough relative to the original image size and the breakpoints one has set in the plugin settings page), then the image will not be created in the cache (the original image will be delivered).

    However, something else might also be relevant to your case. I see that your requests are served via an NginX server which probably acts as a proxy (or a caching server). Is that correct?

    If this is correct, then the NginX server is acting like a small scale CDN. This is an exceptional case for our plugin and it is described in the plugin description page under “CDN/Varnish/external caching services”. Basically, this is a case we do not fully support, due to the way caching servers work: they deliver your images directly, thus your WordPress installation (and our plugin) does not have the opportunity to handle (and resize) your images. Thankfully this does not pose a problem, but it reduces the effectiveness of the plugin.

    Now, for these cases we have created a special mode, called “CDN support”, in the plugin settings page, which you are welcome to enable and test. Unfortunately, this mode is still a bit experimental as it cannot detect CSS background images.

    Let me know if I can help any further with this!

    Cheers,
    Takis

    Hi, Thank you for your kind reply.

    Yes. I am using Fastcgi cache in my server.

    I will test “CDN Option” and waiting for result.

    Thank you.
